--- Comment #27 from Jan Hubicka <hubicka at gcc dot gnu.org> ---
profile_estimate issue is still here, inliner and early inliner issues seems
solved. Seems that ipa_profile just orders the nodes for propagation in wrong
way - we propagate from callers to callees while toposorter is for propagation
opoposite way.
operand_scan seems slow too.
